Subject: Unusual behavior with bash subshell and getopt
Hi everyone,
Today I finally got around to debugging why xsltproc was failing in
packages where man pages were being generated from xml. It is because
/etc/xml/{catalog,docbook} is not being generated by
build-docbook-catalog. The later is a bash script which behave
differently in musl than it does in glibc. I reduced the problem to the
following:
#!/bin/bash
opts=$(getopt -o h --long help -- "$@") || exit 1
eval set -- "${opts}"
while true; do
case $1 in
-h|--help) echo "help" ;;
--) break ;;
esac
shift
done
echo "$@"
When run in glibc this gives:
~ # ./test-getops.sh --help 1 2 3
help
-- 1 2 3
but when run under musl:
~ # ./test-getops.sh --help 1 2 3
Try `getopt --help' for more information.
Everything else about these systems is identical. Any clues?
